Diffusion length solar cell

There are two causes of charge carrier motion and separation in a solar cell: 1. drift of carriers, driven by the electric field, with electrons being pushed one way and holes the other way 2. diffusion of carriers from zones of higher carrier concentration to zones of lower carrier concentration (following a gradient of chemical potential). WebAug 18, 2024 · The diffusion length can then be deduced by fitting the results to ... we emphasize that in solar cells, diffusion lengths of both electrons and holes much larger than the film thickness is ...
